I've got a set of Alembic Activators (Jazz sized) and the matching electronics (Vol/Pan/Filter) that I want to install into a bass with a side mounted jack (Hamer CruiseBass w/ 2Tek for those interested).

I'm also same situation for my Hamer B12-S. The bass has cylindrical stereo phone jack on body side. Almost powered guitars and basses are switched as short circuit (ring to earth). But Alembic instruments use the switch jack. I think following conversion. It's all right?
